Is this in your tank with the black sand? If so oh no my LFS guy might have been right, when we were pricing around for the black sand he had said he wouldn't recommend the black sand because it is high in nitrites, now I don't know if he is right about that, but since we just put ours together I hope it doesn't come to that.

I'm sorry for your loss Hara, hope it's not the sand.

I would like to hear his theory on that. I dont think sand can produce nitrates. Unless there is something in the sand that hinders the growth of denitrifing bacteria. Other than that it would be the grain size. However I know Hara know enough that she would not purchase too large of a grain size to house the fauna.

Anything, just about, can contain nitrates or nitrites or ammonia. The thing is, how does it release it, does it leach slowly back in, does it require another cheical reaction to liberate it? etc...

THe nitrites had been fine up until this issue, so it cannot be the sand.

The lionfish has little red spots, like under the skin blood blisters where each of his spines attaches....does this give anyone a clue? Nitrate poisoning do this?

possible clue

wow... those nitrAtes are really high (aren't they? if 110 isn't high then why have I been fretting over readings in the 20s!! lol)

I found something that may offer a clue:
According to this page, http://puffernet.tripod.com/nitrate-p.html,over at puffer-net :
Quote:
Plant fertilizers may also raise the nitrate levels to toxicity.
You mentioned you are using well water. Do you live in an agricultural area? Spring has sprung and perhaps a near-by farm has used a new fertilizer that has leached it's way into your well water supply...

hmmm but then you'd see this issue in all of your tank's wouldn't you? Have you tested your change water before adding it to the tank?

The well water tests 0 for everything, including phosphates and iron, both chelated and non chelated

Wow, glad to hear about the sand, as you know we didn't listen to the LFS guy, we went for the black sand also, it's still cycling with 44 pounds of live rock. I hope you find out what is happening

Are you using a commercial denitrification process, like sulphur beads or deniballs?
I had exactly the same problem some time ago and I found that my denitrifier had stopped working (as the nitrates were at 0), which prompted the denitrifier to turn into a hydrogen sulphide factory. Two or three drips later and all the fish were dead in the space of 15 minutes (except one clowm), even despite an emergency 60% water change. An expensive lesson!!

Have you noticed any funny smells lately?

Pioneer, was there any effect on the corals? This is where my problem comes in, there are several possible issues, but all the issues I might come up with, would effect the corals. So far this is a mobile invert and fish problem, the corals in Hara's tank are fine.
